Subject: [PATCH 28/55] scsi: Move prototype declaration to appropriate header
 file megaraid/megaraid_sas.h from megaraid/megaraid_sas_fusion.c

Move prototype declarations of function to header file
scsi/megaraid/megaraid_sas.h from megaraid/megaraid_sas_fusion.c because
they are used by more than one file.

This eliminates the following warning in megaraid/megaraid_sas_fusion.c:
drivers/scsi/megaraid/megaraid_sas_base.c:192:21: warning: no previous prototype for ‘megasas_get_cmd’ [-Wmissing-prototypes]
drivers/scsi/megaraid/megaraid_sas_base.c:218:1: warning: no previous prototype for ‘megasas_return_cmd’ [-Wmissing-prototypes]
drivers/scsi/megaraid/megaraid_sas_base.c:878:1: warning: no previous prototype for ‘megasas_issue_polled’ [-Wmissing-prototypes]
drivers/scsi/megaraid/megaraid_sas_base.c:1364:12: warning: no previous prototype for ‘megasas_is_ldio’ [-Wmissing-prototypes]
drivers/scsi/megaraid/megaraid_sas_base.c:1639:6: warning: no previous prototype for ‘megaraid_sas_kill_hba’ [-Wmissing-prototypes]
drivers/scsi/megaraid/megaraid_sas_base.c:1659:1: warning: no previous prototype for ‘megasas_check_and_restore_queue_depth’ [-Wmissing-prototypes]
drivers/scsi/megaraid/megaraid_sas_base.c:3030:6: warning: no previous prototype for ‘megasas_free_cmds’ [-Wmissing-prototypes]
drivers/scsi/megaraid/megaraid_sas_base.c:3066:5: warning: no previous prototype for ‘megasas_alloc_cmds’ [-Wmissing-prototypes]
